Geotagging of images?
Just thinking out loud here, but are we using our photographs in Commons to maximum advantage?
Reason I ask is that there is more and more geographic tagging of pictures starting to
happen (e.g. http://www.panoramio.com/ ). If we take a large repository of images
like Commons, and add geographic tags (long + lat) to those images (maybe with a bot
based on the that articles that include them, and that in turn have geographic tags included),
then you could very quickly build a very large and powerful repository of images, that are
tied to specific points on the globe .... which could be, y'know, be kinda cool, because
then you could potentially search for images on Commons based on location, and it could
come back with a whole list of images, in progressively increasing distance from the point
that you just specified.
So using London as an example, say you search for a point near Big Ben (by clicking on a
map or something), and you'd get back pictures of Big Ben, then the Houses of Parliament, and
the Thames River, then the London Eye, and so forth - so you would get an immersive image
search, perhaps in some ways more powerful than what we have currently.
But that's just half of it - because then you could do it the other way around
too, and you could add a geographic tag to articles, and then it could suggest some pictures
that you might want to add to your article, because they're close to the point you just
specified. And the best bit: No language or translation problems - because Longitude and
Latitude are universal, language-neutral things - so it would help _every_ Wikipedia.
Of course, to do this stuff, it would be nice to have some sort of structure to specifying
Long + Lat, possibly something more low-level than just a template, because you'd want it
to be readily and quickly searchable & indexable. And if you're going to do it for images,
maybe it should be done for articles too - that way you could say "find me other articles that
are about somewhere close to the article that I am currently looking at", and it could work
automatically, without having to manually add links. _Maybe_ you'd be looking at extra columns
in the database, which gets tricky, because it's extra baggage that might not relevant to
